# How do you find the percent of increase from 45 m to 54 m?

May 15, 2018

Just divide to find that the percent increase is 20%.

#### Explanation:

To find the percent increase, take the value you end with, and divide it by the number you started with.

In this example:

$\left(54 \text{m")/(45"m}\right)$

You can cancel the units:

$\left(54 \textcolor{red}{\cancel{\text{m")))/(45color(red)(cancel("m}}}\right)$

$\frac{54}{45} = \frac{6}{5} = 1.2$

Finally, convert $1.2$ into a percent:

1.2=120%

As you started with 100%, subtract that to find your percent increase.

120%-100%=color(red)(20%
